Application filad october 6, 1902 I0 aZZ whom, it may concern:

Be it known that I, ALLEN GARDINER IN- GALLS, a subject of the King of Great Britain, residing atMontreal, in the District of Montreal, Province of Quebec, Canada, have inventedcertain new and useful Improvements in Attachments for Furnaces and the Like, of which the following is a specification.

My invention relates to attachments to furnaces and the like; and the object of the invention is to devise an appliance by means of which water will be automatically fed to a fire in a filtered state andin such a manner as to cause it to assume its spheroidal form on reaching an incandescent bed of fuel and whereby the consumption of ordinary fuel will be lessened materially in the provisionof the supplemental fuel-water in its spheroidal form; and it consists, essentially, of a plurality of vessels attached to the side of a heater, through which a continuous stream of water is designed to flow, a minute water-wheel introduced between said vessels, a nozzle suitably connected to one of the said vessels and projecting through the furnace-wall, a frame designed to hold the said nozzle, and suitable means for transmitting power from the waterwheel to impart a twirling motion to the nozzle, the various parts being constructed in detail as herein after more particularlydescribed.

Figure 1 is a perspective View of my device attached to the side of a furnace-wall. Fig. 2 is a sectional view of the filter vessel. Fig. 3 is a sectional view of the water-wheel and casing. Fig. 4 is'a detail of the counterpoiseweights, nozzle, and frame. Fig. 5 is a sectional view of the swivel arrangement of rings. Fig. 6 is a sectional view of the adjustable and pivotal points. Fig. 7 is a detail of the alternative form of frame and nozzle.

Like characters of reference indicate corresponding parts in each figure.

a is the filter vessel, and Z) the brackets attaching said filter vessel to the frame 0.

d is a flushing-cock located to the lower end of the filter vessel a. V

e is a pipe connecting the filter vessel to the main water-supply.

f is a porous-clay lining loosely fitting in Berial No. 126,221. No morleLl the filter vessel or and closed at the top and open at the bottom and resting on the projecting ledge g of thebase h of the said filter vessel a.

, It will be seen that any water entering the filter vessel a through the pipe 6 must first pass up into the interior of the porous clay lining f and from there penetrate through the said lining at the sides and top into the filter vessel (1.

Z is a water-Wheel having the paddles m designed to rotate the shaft n, which turns in suitable roller-bearings. v

o is a worm-wheel keyed to the shaft 71 outside the casing j;

19 is a rod having the worm end and the worm r at its lower end and turning in the brackets s from the frame 0. V

The rodjp is provided with the rings or nuts Vt above and below the lower bracket 8.

"u is a transparent receptacle connected by means of the pipe 1* to the casingj.

0c is a pipe leading down through the-pipe o from the exhaust-opening 20 into the interior of the receptacleu.

y is an overfiowpipe through the top of the receptacle .u.

The exhaust-water from the casing j drips down the central pipe or: into the interior of the receptacle a. f

z is the reduced lower end of the receptacle ,u and is provided with the orifice 2 at the bottom thereof.

3 is a cock secured to the frame 0 and provided with the projecting pipes 4 and 5 from each side.

6 is a tube connecting the reduced lower end z with the pipe 4, leading through the cock 3.

7 is a nozzle having a lava-tipped point 8, provided with very minute orifices 9, designed .to direct water in various directions.

10 is a flexible tube designed to connect the pipe 5, leading from the cock 3 and the nozzle 7, and is supported from the frame intermediate of its length by the staple 11.

g at its upper- 12 is an orifice in the furnace-wall above the fire, having the stationary ring 13 inserted therein.

let represents screws having the lava tips 15 tapering to a point.

The screws 14 are designed to be inserted through the ring 13 diametrically opposite one to the other and pointing inwardly toward the center of the ring.

16 is a ring provided with pivotal-point bearings 17, designed to receive the lava tips 15.

18 represents screws also provided with lava tips 19, tapering to a point and inserted through the ring 16 diametrically opposite one to the other and pointing inwardly toward the center of the ring.

20 is a ring provided with the pivotal-point bearings 21, designed to receive the lava tips 19.

22 and 23 are rods inserted into orifices diametrically opposite one to the other in the edge of the ring 20.

24 is a spring-clip designed to hold the nozzle 7 in position between the rods 22 and 23 and having orifices 25 and 26 for the rods 22 and 23 to pass through. The rod 23 terminates at the outer edge of the orifice 26, and the rod 22 passes through the orifice 25 and extends rearwardly. It will be thus seen that a tube or nozzle inserted in the central orifice formed by the ring 20 may be given an oscillatory motion through the sWivelly-arranged rings 16 and 20.

27, 28, and 29 are arms projecting from a common hub 30, and 31 represents counterpoise-weights terminating the arms 27 and 28.

32 is a shaft jonrnaled in the brackets from the lower end of the frame 0.

3a is a worm-wheel securely keyed to the shaft 32 and designed to mesh with the worm r. The hub is also securely keyed to the shaft The nozzle 7, when held to the rod has its nose or tip 8 projecting through the ring 20 into the interior of the fire-box. The rod 22 also at its inner end is inserted in an orifice in the said ring 20.

It must be here understood that I may adopt other methods of holding the nozzle. For instance, as shown in Fig. 7, I have provided a ring 35, having a set-screw 36 inserted diametrically therethrough and orifices 37 and 38 designed to receive the rods 22 and 23, the latter rod terminating in the rings and 20 and the rod 22 extending through the arm 29, as aforesaid. In this method the nozzle is inserted through the ring 35 and similarly, as described, through the ring 20. The set-screw 36 is then screwed down firmly against the said nozzle in order to prevent on the turning of the shaft 32, which is operated through its worm-and-wheel onnection with the rod 17.

is a valve placed, if desirable, at the outlet of the filter vessel and is designed to control the egress of water.

The rod 1) is preferably provided with a stationary casing 41.

Having described the various parts involved in my invention, I shall now more particularly explain the operation thereof.

The water is turned on from the main water-supply and is allowed to flow through the pipe 6 to the interior of the porous-clay lining f. The water penetrates the porous lining through the sides and top thereof and fills the filter vessel (1. The water is now in a filtered state, and it passes on up through a suitable opening at the top of the filter vessel a into the pipe 2', and flowing on through the said pipe the water enters the water-wheel casing through the minute opening k. This causes a very fine jet ofwater to enter which impinges against the paddles m. The continuous impinging of water through the orifice it upon the paddles m causes them, and consequently the water-Wheel, to rotate in the interior of the casing j. The rotation of the water-wheel Z turns the shaft or, which causes the worm-wheel o to revolve. The worm-wheel 0, meshing with the upper worm q, operates the rod 1), which in turn, as before explained, operates the worm-wheel 34 through the meshing of the latter with the worm r. The revolving of the worm-wheel 34 turns the shaft 32, and as the hub 30 is securely fixed thereon the arms 27, 28, and 29 rotate therewith. The rod 22 is loosely held in the orifice 39 in the arm 29 at one end and at the other in the ring 20. Consequently in the rotation of the arm 29 the rearward end of the nozzle is carried with it, the counterpoise-weights 31 being provided to balance the weight of the said frame. The rearward end of the nozzle rotating with the arm 29 causes a twirling motion to the point of the nozzle, which is, as herein explained, held securely to the rod, and as the point of the nozzle thus moves the rings 16 and 20 move with it in any direction because of the rightangular pivotal arrangement of the same practically holding the tip of the nozzle in a swivel arrangement of rings. The water which has been spurting into the casing must have an outlet, and this is provided in the exhaust-opening w.

The water exhausts through this opening into the pipe or, whichcarries it down into the interior of the receptacle u. The cock 3 is turned so as to cut off the passage of water therethrough, and thus allow the receptacle a to fill up to a desired level, and so soon as this level has been reached the cock 3 is opened and the water allowed to pass therethrough from the receptacle u down through the tube 6 into the nozzle 7, finding egress therefrom through the minute orifices 9. It is scattered in vary ing directions in the fire-box, guided by the oscillatory motion of the tip of the nozzle and the angular arrangement of the orifices 9 one to the other. The escape of water through the orifices 9 in the nozzle 7 is designed to be equal to the ingress of water to the receptacle a from the exhaust of the water-wheel chamber, a certain water-level being maintained in the receptacle M, which practically serves the purpose of a gage. The water exhausting from the casing j will thus find its way to the fire-box, in which it is proposed to have an incandescent bed of fuel. The twirling motion of the tip of the nozzle sends this water into the fire in such a manner as to cause it to separate in minute globules. Theseglobulesfall to the incandescent bed of fuel and there suspend in spheroidal form. The water in its spheroidal form wastes away into 11 0 gas and is consumed by the fire, thus supplementing the fuel already in the fire-box and causing a very great increase in the generation of heat from the fire.

The regulation of this device is a very important matter, which needs a little care at first to ascertain exactly to what level the water must be maintained in the receptacle u. Upon ascertaining this fact the subsequent care is practically nothing, as the machine will automatically govern itself, only requiring the one stream of water, which can be obtained from the main water-supply.
